Abstract: Support d'enregistrement magnétique contenant en tant que liant un polymère modifié préparé par polymérisation à greffe d'un composé polymérisable non saturé possédant un groupe d'acides sulphonique ou un groupe d'un sel métallique de l'acide sulphonique sur un polymère par irradiation avec une radiation. Ce polymère modifié présente de bonnes caractéristiques d'adhésion de la poudre magnétique et améliore les caractéristiques de dispersivité et de remplissage de la poudre magnétique à cause de la présence du groupe d'acides sulphoniques ou du groupe de sels métalliques d'acides sulphoniques. Le support d'enregistrement magnétique possède ainsi une excellente résistance. En outre, étant donné que le polymère modifié peut être obtenu par polymérisation à greffe utilisant une radiation, le polymère à modifier peut être sélectionné à partir d'une gamme étendue de composés, de sorte que le support d'enregistrement magnétique peut être produit par un procédé industriel utilisable dans la pratique.

IPC: F04D13/10

Abstract: A motor-pump unit for submerging down a well, e.g. an oil well, comprises a motor portion driving a pump portion. The motor portion is filled with fluid to prevent ingress of the surrounding medium which the pump portion pumps. The fluid is maintained at a higher pressure than the surrounding medium by including a flexible tank filled with fluid and in communication with the fluid in the motor portion. The flexible tank is compressed both by the surrounding medium and by resilient compression means so that the pressure inside the motor is higher than the surrounding pressure, thereby ensuring any leakage is outwardly from the motor. Down the well the temperature rises causing the fluid to expand, so the flexible tank is left substantially empty when the unit is prepared at the surface prior to lowering. If a large rise in temperature is to be expected, a resilient compression means which provides adequate excess pressure near the top of the well as the unit is lowered, will provide too much excess pressure at operating depths, and similarly compression means which provide adequate excess pressure at operating depths do not supply enough near the surface. This problem is solved by providing compression means which includes a first spring (79) and a second spring (80) so disposed that the flexible tank (66) is subjected to the sum of their resilient thrusts, with the second spring applying its thrust via release means (83 to 88) which cause said second spring to be released and to relax once its displacement reaches a predetermined value.

Abstract: A transmission system for transmitting binary data symbols. For the transmission of data symbols via systems which, the physical transmission medium included, are not suitable, or are poorly suitable for the transmission of low frequencies it is known to use bi-phase modulation. This method is however not optimal as regards the signal-to-noise ratio and the intersymbol interference. 
     A transmission system is described in which an optimum detection is enabled through the use of bi-phase encoding of the binary data symbols and special filter means, which detection is highly independent of the frequency response of the constituent parts of the transmission system and/or the physical transmission medium for low frequencies. 
     This system may be used in optical communication systems as well as in systems for digital transmission via cables, the undisturbed, simultaneous transmission of an independent base-band signal being possible.

Abstract: A system for providing telephone service to a subscriber has at least one unconventional telephone (40) and at least one master or interface unit (20) which is electrically connected between the telephone (40) and the central office. The operation of the telephone hook switch (44) in combination with the operation of the dialing information entering means (42) on the telephone provides changes in the impedance of the telephone (40). The master unit (20) responds to these impedance changes to generate signals interpretable as dialing to the central office. When the telephone (40) is on-hook the master unit (20) responds to ringing from the C.O. and converts that signal to a signal which is used by the telephone (40) to alert the subscriber.
